Hello togetherI use the following library to create random numbers:- LibraryThe sample project runs on my NUCLEO-144 H743ZI. The problem is that the same byte array (RandomString) is generated at every time. *****************************************...
In the code below I have AES GCM correctly decrypting data using the Cryptolib. I am trying to decrypt the same data using the HAL_CRYP_AES_XXXX functions and it isn't working.Key is 32 bytes. iv is 12 bytes. header data (aad) is 3 bytes. message...
Hello All,We have designed a Custom Board with STM32F777 MCU chip and are using Atollic Truestudio with ST Micro's CubeMX for development.I have implemented a USB boot loader for the same hardware which is working fine with the Custom Board.Now i wan...
Hi,I requested a download access to X-CUBE-SBSFU firmware about two weeks ago but I didn't get a reply yet. Is there something else I should do ?
Main is entered,(for testing I enable the GPIO and turn on an LED to validate that cpu execution has entered main() --- then I set up the PLL, and GPIO - then test if the MCU has option byte set for Level 1 - if not I set it.I reset the device and it...
Hi,Upgrading to version 2.2.0 i get this error using the option " --mergesbsfu" (Add a binary header and a sbsfu segment to an elf file):arm-none-eabi-gcc -o "STM32F769I-Discovery_AWS.elf" @"objects.list" -mcpu=cortex-m7 -T"../STM32F769NIHx_FLASH.l...
I am using multiple MCUs: STM32F733, STM32L433, STM32L443.In STM32CubeExpansion_Crypto_V3.1.0 I am using the software AES CTR encryption (Inc/AES/CTR/aes_ctr.h). I use AES_CTR_Encrypt_Init / AES_CTR_Encrypt_Append / AES_CTR_Encrypt_Finish methods. Th...
Hi ,I am coding for STM32F207 for first time so I do not understand Why is STM32F207 processor loading 16 bit thumb instruction where as the Function pointer is 32-bit . is this ((void (*)(void))g_ulTransferAddress)() wrong ? As per our Project requi...
SBSFU considers the secure boot as the root of trust. If we develop the firmware and manufacture the products in a factory (I assume that the firmware should be programmed during the manufacturing in the factory), how to guarantee the secure boot is ...
I have a large application image running on the STM32F427. The image is more than 1M bytes, which make it impossible for dual-image. From ST's document, for single-image, "The user application cannot download a new firmware image: the local download ...
